Even so, comparing experience method with qualitative analysis, heat treatment simulation by computer makes great progress.
3.2 Establishment and integration of models
The development procedure for die and mould involves design,manufacture, heat treatment, assembly, maintenance and so on. They should have own database and mode1. They are in series with each other by the entity—relation model. Through establishing and employing dynamic inference mechanism, the aim of optimizing design can be achieved, The relation between product model and other models was built. The product model will change in case the cell model changes. In fact, it belongs to the relation of data with die and mould. After heat treatment model is integrated into the system, it is no more an isolated unit but a member which is close to other models in the system. After searching, calculating and reasoning from the heat treatment database, procedure for heat treatment, which is restricted by geometric model, manufacture model for die and mould and by cost and property, is obtained. If the restriction is disobeyed, the system will send out the interpretative warning.
All design cells are connected by communication network.
3.3 Management and harmony among members
The complexity of die and mould requires closely cooperating among item groups. Because each member is short of global consideration for die and mould development, they need to be managed and harmonized. Firstly,each item group should define its own control condition and resource requested, and learn of the request of up-and-down working procedure in order to avoid conflict. Secondly, development plan should be made out and monitor mechanism should be established. The obstruction can be duly excluded in case the development is hindered.
Agile management and harmony redound to communicating information, increasing efficiency, and reducing redundancy. Meanwhile it is beneficial for exciting creativity, clearing conflict and making the best of resource.
4 Conclusions
(1) Heat treatment CAD/CAE has been integrated into concurrent design for die and mould and heat treatment is graphed, which can increase efficiency, easily discover problems and clear conflicts.
(2) Die and mould development is performed on the same platform.When the heat treatment process is made out, designers can obtain correlative information and transfer self-information to other design departments on the platform.
(3) Making out correct development schedule and adjusting it in time can enormously shorten the development period and reduce cost.
